Penny Lancaster shares heart-warming message from Rod Stewart after health struggles

Sir Rod Stewart's wife, Penny Lancaster, has emotionally revealed the rock legend's fears over his recent health scare that threatened to end the chances of one major career highlight.

The iconic singer battled through a difficult month, culminating in a triumphant return to Glastonbury Festival last month, - a moment he'll no doubt cherish as a pinnacle of his illustrious career.

Rod Stewart's much-anticipated comeback on Glastonbury's Pyramid Stage was shrouded in uncertainty after health issues forced him to reschedule and cancel several performances.

In a candid Instagram update earlier last month, Sir Rod informed his fans about the postponement and cancellation of his US tour dates, having been struck down by a severe strain of influenza, which Penny referred to as the "worst" kind.

He announced the cancellation of three Las Vegas shows and one in Lake Tahoe, while rescheduling his June 12 performance in Rancho Mirage, California, and his June 15 concert in Paso Robles, California, for September 20 and 21.

However, speaking to Hello! magazine, Penny Lancaster shared how Sir Rod had doubted his ability to recover in time for his Glastonbury appearance, confessing to her: "I don't think I'm going to be well enough. I tried my voice out, and it's not working."

Defying all odds, Sir Rod Stewart made a triumphant return to Glastonbury on June 29, taking the Legends Slot by storm on the Pyramid Stage.

Penny Lancaster was there to greet her husband with open arms after his set. Recalling him having the "biggest grinning face," she proudly said, "You did it," as he came off stage.

However, eager not to take all of the credit, he quickly turned the praise around, affectionately telling Penny: "I couldn't have done it without you."

The couple's romance began back in 1999, following Sir Rod's separation from his former wife, Rachel Hunter. After an eight-year relationship, they exchanged vows in the idyllic setting of Portofino, Italy, on June 16, 2007.

Following a bout of what Penny described as the "worst" flu, Sir Rod is now gearing up to take his music on a global tour.

Fans can look forward to seeing him perform across the US, and then in Germany, Switzerland, and Austria later this year.
